      More Details Abstract Fulltext PDF

      A homologous series with carboxy (-COO-) and azo (-N=N-), as central groups have been synthesised by treating 4-(4′-n-alkoxy benzoyl) chloride with 4-hydroxy phenylazo-4′-methyl benzenes. All the homologues of the series are mesomorphic in nature. The first eight members of the series are nematogenic and the remaining members exhibit smectic and nematic character with high melting behaviour and wide mesomorphic range. The usual odd-even effect does not predominantly appear in nematic isotropic transition curves but it appears to some extent in the first four homologues. Thermal stabilities are comparable with structurally similar known series.
